Ameerul Momineen Fateh Kaysar o Kisra Saydna Umar ibn al Khattab عليه السلام once severely rebuked a man who forced his servants to stand while he sat to eat.
Saydna Ibn Abbas reported that Saydna passed by some people one day who were eating while their servants were standing.
Saydna Umar said, “Why do I not see your servants eating with you? Do you not desire them?” A man said, “No, by Allah, O leader of the faithful. Rather, we have preference over them.” Saydna Umar became very angry, then he said:
ما لقومٍ يستأثرون على خُدَّامهم فَعَلَ الله تعالى بهم وفَعَلَ
"What is the matter with people who prefer themselves over their servants? Allah Almighty will deal with them and it is done!"
Then Umar said to the servants, “Sit down and eat.” The servants sat to eat and the leader of the faithful did not eat.
[Musnad al Farooq 2/247, By Imam Ibn Kathir]
